Patent DE-2412540-A1 (DE)
Title: Cable connecting sleeve for insulated wires - with internal sharp pointed thread for making contacts
Inventor: BIEBACH ERWIN
IPC: H01R4/20
Filed: 1974-03-15
Abstract: The connector is particularly intended for joining cores in telephone cables without the need to remove the insulation from the wires. It comprises a tubular metal contact sleeve with an internal thread form with sharp edges. These cut through the cable core insulation and bite into the metal of the core when the connector is compressed after inserting the two cores into the bore. The outside is covered with an insulating sleeve, typically an irradiated polymer, which is shrunk on before use. A thermoplastic filler may also be formed around the connector, under the insulation sleeve, to seal off one end and provide a skirt at the other.

Title: Air conditioning unit vent closure valves - for adjusting quantity of air introduced into room without altering flow conditions
Inventor: REGENSCHEIT BRUNO
IPC: F24F13/12
Filed: 1974-03-20
Abstract: Vent closure valves comprise individual, independently slidable, short elements having an absolute length of about 50-200 mm., for closing the vent in sections. Inside the vent housing is a guide member of segment-shaped section which is adjustable pivotally about a longitudinal axis to fix the direction of flow of incoming air. By closing only sections of the vent, air speed in adjacent sections is maintained and therefore also the Archimedean number, which is the ratio of gravity forces to inertia forces in the jet of air, preventing the air from descending before it has travelled far enough.
Patent DE-2416750-A1 (DE)
Title: Rounding off machine for die edges - has horizontal working slide of controllable stroke length with suspended collet holders
Inventor: SCHMALE FRITZ
IPC: B24B5/14
Filed: 1974-04-05
Abstract: The rounding off machine is for rounding off the edges of drawing dies and orifices by means of a horizontally moved working slide whose stroke length is controllable and in which are suspended replaceable collet holders reinforced with weights with a needle ground to an angle. These operate the workpieces which have a diamond powder mixture and are located at the top end of an individually driven spindle in an adaptor and this rounds off the edges. The equality of the edge rounding is guaranteed by a built-in timer which automatically cuts off all spindles after the given time.

Title: Universal spreader, brace, spacer in concrete construction - with reinforcing bars locked as desired by rotatable clamp components
Inventor: HUEBNER WALTER
IPC: E04C5/20
Filed: 1974-07-17
Abstract: By use of the multi-purpose spreader, clamping brace and space-retainer, reinforcing bars can be selectively locked in position as desired by means of clamping components which can be rotated. Clamps with a broad action influence the stability of reinforcing units being handled, and make it possible to transport or lay stable connections, involving the use of a crane, by means of horizontal and vertical checks. Suitable spreader-spacers can be led into matching recesses in the clamps, and held fast by turning in guideways.

Title: Water desalination and purificn by solar energy - in osmosis plant powered by turbine generator in closed solar cell circuit
IPC: C02F1/44
Filed: 1975-03-08
Abstract: A conversion plant from solar energy into thermal energy for the desalination or purification of salt or contaminated water uses in the primary circuit it a fluid with a heat of vaporisation of 0.5kWh/kg. This circulates from the solar cell to a steam turbine, which drives a generator, and a condenser. The crude water is preheated in the condenser and passes into a reverse osmosis or electrodialysis plant. The pump in this circuit is driven by a motor, powdered by the generator. A plant operating on this cycle produces 10-25 times the amt. of drinking water per m2 of solar collector surface area. The plant operates completely independent of additional energy supplies.

Title: Readily collapsible shelving with easily interconnected uprights - uses common connecting pins with slit ends for engaging in aligned tapering blind holes
Inventor: SEEDORFF GERHARD
IPC: A47B87/02
Filed: 1975-09-15
Abstract: The knock-down shelving comprises a system of vertical uprights (1) connected together by shelves (2) or transverse webs wherein the butt edges of the uprights are each provided with an inwardly tapering blind hole (4) so that a common connecting pin (3) can be inserted into two blind holes which are in alignment. The opposite ends of each connecting pin is provided with a cross-shaped slot (6) and the cross-sectional area of the pin corresponds to the cross-section of the opening to the blind hole. Thus, when inserting the pins into the tapering blind holes they fit tighter and tighter against the sides until they are resiliently clamped, with the ends of the pins being compressed on account of the slots (6).

Title: Cam operated clamping punches for splicing film - have integral cutters for shearing off bonding tape for heat welding
Inventor: KOMENDA FRANZ
IPC: G11B27/06
Filed: 1975-12-20
Abstract: The motor driven splicing fixture for joining ends of film (3) has two opposing clamping punches (4,5) which are electrically heated.

Title: Hydrogen isotopes separated from gas phases - by selective permeation then reducing reaction with metal oxide
Inventor: MORLOCK GUENTER DIPL PHYS
IPC: C01B4/00
Filed: 1975-12-22
Abstract: The parent patent describes a device for separating hydrogen isotopes from gas phases, consisting of a closed vessel with walls selectively permeable to hydrogen isotopes and contg. a compact, pressure-resistant packing of metal powder, metal sponge or the like, (e.g. titanium) which binds the hydrogen isotopes. Both the walls and the packing are maintained electrically at the correct operating temperature. In this addn. a metal oxide packing, e.g. copper oxide, is used instead. Used esp. for hydrogen isotope (tritium) separation in a nuclear power plant or to remove hydrogen to reduce explosion risk. High reliability esp. during shock waves in a reactor incident, can be obtd. by using a large number of devices in small sizes, e.g. near the roof of a gas space. This small size production is also inexpensive.

Title: Proc. for incg. digestibility of cellulosic plant matter to ruminants - by oxidn. in the presence of metal and acid catalysts followed by hydrolysis
Inventor: JELKS JAMES W
IPC: A23K10/32
Filed: 1976-02-16
Abstract: The digestibility of cellulosic plant matter to ruminants is increased by mixing the particulate matter with water, an acid catalyst selected from carbonic, sulphuric, phosphoric, hydrochloric and acetic acids to give a pH of 3 and a metal catalyst selected from iron, ferric chloride, ferric sulphate, ferric nitrate, manganese and non-toxic manganese salts, subjecting the mixt. to an oxygen partial pressure of about 20-30 psig at about 105 degrees-110 degrees C for 12-20 mins., blowing off resulting gases of oxidation and hydrolyzing the resulting oxidized mixt. at elevated temp. e.g. 180 degrees c, and 135-150 psig pressure under satd. steam conditions. In the oxidn. at least a portion of the lignin-cellulose bonds are broken and at least a portion of the cellulose molecules fragmented, and in the hydrolysis at least a portion of the cellulose is converted into saccharides and saccharide acids. The process may be applied to matter such as corncobs, rice halls, bagasse, wheat straw, oat straw, rice straw and the trunks, limbs, stems and leaves of tree and shrubs. This is less specific regarding the nature of the acid and metal catalysts and the timeS, pressures and temperatures.

Title: Gum massaging toothbrush with two sets of bristles - has bristles at right angles pointing toward each other with shanks in V-shape
Inventor: NOERTHEMANN KARL-HEINZ
IPC: A61C17/22
Filed: 1976-03-02
Abstract: A tooth brush has a shaft, on whose front end are two brush shanks where the shanks are opposite ina V-shaped manner and form a gap between them. Specifically, the shaft, at its rear end, is so curved to an arc (8) to the brush-carrying head (2 & 3) that the shaft end (10) and the middle of the two part head lie on a common axis X-Y (5). The fork transition (30) has a larger taper to the left and right at equal amounts of the shaft transition. The free ends of the shanks (2, 3) have a bevel (11) to the shaft side (10). Viewed from the working side of the brush shank the brush arrangement forms a rhombus such that four brush bundles (7) are arranged at the corner points (27) and then can be introduced at both shanks at different angles (33, 34).
